Drum Screen

drum screen

Introduction of drum screen

This series of drum screen is common classifying equipment used in processing minerals such as ferrous metals including hematite & magnetite And nonferrous metals including Lead, Zinc, Gold and Silver etc. This machine works in a recirculating network with Ball mill, which can upgrade the fineness of ferrous and nonferrous metals. Its efficiency is twice as that of spiral classifier.

Drum shaking screen equipment is an important mineral processing machine, it's applicable to screening of metallurgical sintered ore is an ideal apparatus to replace the manual screen for reducing labor intensity for operator and improving comparability and correctness of screening. It features compact structure, easy operation and reliable running among others. The drum screen is complete with electronic counting controller, allowing test materials to have the correct screening frequency and avoiding human errors arising from manual operation of screen.

Structure and principle

Drum screen consists of motor, decelerator, rotordrive, chassis, seal cap, inlet and outlet. Material feeds into the drum, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.
